Abstract
The utility model provides a mechanical actuating mechanism which is mainly composed of a gear (3), a gear (5), a motor (1), etc. The gear (3) is fixed on a machine frame (9) by a rotary axle. The gear (5) does not have a fixed rotary axle, and is meshed with the gear (3). A belt pulley (4) on the gear (5) is connected to the motor (1) through a driving belt (2). Two semi-axles (7) are fixed on the machine frame (9), and extend into a convex ring (6) on the gear (5) from both sides. The gear (5) is additionally held by a supporting wheel (8). When the utility model works, the gear (5) produces a lever force which is suitable for the transmission work of low speed and high load to the gear (3) by using the semi-axles (7) as fulcra. Load can be driven through a power output shaft (10).
Description
The utility model relates to a kind of mechanical transmission, promptly a kind of lever energizing driver structure that can significantly improve machinery driving efficiency.
At present, the transmission device kind is a lot, but all is to be connected each other by belt, chain or gear etc. by power unit and transmission part or workpiece to conduct power mostly, and these passive components all are the dead axle rotatable parts mostly.The biography of above-mentioned transmission device is put efficient, and particularly the moment of torsion of transmission does not often satisfy people's needs.
The purpose of this utility model is that a kind of transmission efficiency of development is higher, the driving mechanism that driving torque is bigger.
The foregoing invention purpose is that following technological scheme realizes that two gears that are meshed are arranged, and one is fixed on the frame by rotating shaft; Another no fixed rotating shaft, and link to each other with power source; The circle prominent ring concentric with gear arranged on the gear bi-side of no stationary axle; Have two to be fixed on the machine frame at two sides, the rotation semiaxis that its shaft axis is parallel with Gear axis inserts prominent ring from both sides, and contacts with prominent ring inwall.
Adopt technique scheme, power equipments such as motor or diesel engine are linked to each other with the gear of no stationary axle by driving belt, during work, driving belt pulls to power equipment one side to this gear, and two semiaxis are as fulcrum, this pulling force is passed to point of mesh by opposite direction, form the such leverage of Fig. 3, rotate outputting power thereby stirred shaftgear.Because the effect of this lever, this mechanism can produce the effect of tending to act preferably.
Introduce two kinds of embodiments below in conjunction with accompanying drawing:
Fig. 1 is the plan view of this driving mechanism, and Fig. 2 is its plan view, and Fig. 3 is the free-body diagram of leverage.
As can be seen, this driving mechanism is mainly by no stationary axle gear (5) with fixed rotating shaft is arranged is that gear (3) and frame parts such as (9) are formed.On the axis of gear (5), a drive wheel (4) that is linked to each other by driving belt (2) with motor (1) is arranged, gear (3) is meshed with gear (5), gear (5) is last, gear (3) is following, and gear (3) is fixed on the frame by rotating shaft, and stretches out pto (10).Gear (5) has an angle with the axial connecting line and the axle center vertical line of gear (3), generally is advisable with 15 degree.In gear (3) both sides, be provided with the prominent ring (6) concentric with gear (3), have two rotation semiaxis (7) that link to each other with frame to insert prominent ring (6) from both sides, its semiaxis cylindrical contacts with prominent ring (6) inwall with prominent ring (6) inwall intersection at the axle center vertical line of gear (5).Prominent ring (6) external diameter also can replace the moving wheel (4) that passes to link to each other with line belt.In order to prevent gear (5) landing downwards, on outer rim, be provided with a supporting wheel that links to each other with frame (9).When motor is worked, rotate by direction as shown, gear (5) can be pulled to motor one side, at this moment, two semiaxis (7) are prominent ring (6) inwall of Support Gear (5) round about, gear (5) can produce the power stir to gear (3), thereby gear (3) is rotated and does work.
As shown in Figure 3, ABC is three points on the gear (5), the A point is subjected to the tensile force f 1 of driving belt (2), the B point is the support force F2 that prominent ring inwall is subjected to semiaxis, the C point is gear (5) is subjected to gear (3) in contact points support force F3, same gear (5) also has one to equate and the opposite Driving force of direction with F3 to gear (3), thereby makes gear (3) rotation and work.Because the distance of AB is greater than the distance of BC, thereby the power of F3 can this shows that this driving mechanism has the boosting function of lever greater than F1, thereby applicable to the bigger transmission work of load.
Claims (2)
1, the utility model relates to a kind of lever booster, it is characterized in that: two gears that are meshed are arranged, and its middle gear (3) is fixed on the frame (9) by rotating shaft, the no fixed rotating shaft of gear (5), and link to each other with power source; On gear (5) bi-side, have and the prominent ring of the concentric circle of gear (5) (6), the parallel axes of two axis and gear (5) is arranged and be fixed on rotation semiaxis (7) on the frame (9), insert prominent ring (6) from both sides, and contact in prominent (6) inwall that encircles.
2, lever booster according to claim 1 is characterized in that: two meshed gears (3) and (5), when placing up and down, the line at two centers and center vertical line are an angle.
